PUNCHING AND EYELETING MACHINE.

SPECIFICATION forming part of Letters Patent No. 696,21 1, dated March 25, 1902. Application tiled October 1, 1900. Renewed August l0, 1901. Serial No. 71,636. (No model.)

and city and State of New York, have in-Kk vented certain new and useful Improvements in Punching and EyeletingMachines, of whichk the following is a specification.

This invention relates to machines adapted to punch the material and set an eyelet in the hole punched; and the object of the invention is to provide a simple machine wherein the punching and setting operations are performed successively, but at one operation ot' the machine. p

In the accompanying drawings, which illustrate an embodiment of the invention, Figure l is a side elevation of the entire machine on a relatively small scale and showing the parts in their normal condition of rest. Fig. 2 is a front elevation of the upper part or head of the machine on a larger scale than Fig. l, also showing the parts in their normal condition of rest. Figs. 3 anda are respectively a side and front elevation of the upper part or head of the machine on the same scale as Fig. 2V and showing the parts in the position of setting the eyelet. Fig. 5 is a plan of the supporting-plate for the material. Fig. 6 is a cross-section of the eyelet-set and its guide- Way. Fig. 7 is a sectional view of the head of the toggle-operating rod. Fig. 8 is a view of the eyelet-set, detached and partly in section. Fig. 9 is a fragmentary view illustrating a construction of the arm 19, d ierent somewhat from that seen in the principal views.,

The general construction of the machine as herein shown and its operation will be briefly described. A

The head of the machine is mounted on a column or base, at the lower part of which is an operating-treadle to be depressed by the foot. The eyelets are in an oscillating box or magazine carried on the upper end of an inclined sliding eyelet-track. On the head is a bed or plateto support the material to be punched and to receive the eyelets, andthe punch is mounted in a guide above and is depressedin punching. The eyelet-set is guided below and moves upward insetting, being operated by a special toggle device from thev treadle. As the eyelet-set moves upward the punch is lirst driven downward through the material and then retracted. Then the set f takes an eyelet from the track and moves the latter, back out of its path, and thenin its continued upward movement the set swings laterally an arm above, which carries the punch and the eyelet setting or clenching anvil, shifting the punch to one side and putting the anvil into alinement with the upwardly-moving set. `The termination of the movement of the set clenches or rivets the eyelet.

1 is the head of the machine, which is mounted on the column 2. On the column is fulcrumed the treadle 3, which may have a counterweight 4. and a retracting-spring 5. On the head is secured a supporting-plate G,

vand in a vertical guideway in the head below is mounted the eyelet-set 7, adapted to move up and down. To.operate this set, a rod 8, coupled at one extremity to the pedal, is coupled at' the other extremity to the knuckle of a toggle consisting of two links 9 and 9a. The lower link 9 is coupled to the stationary head l, and the upper link 9a is coupled to the eyelet-set 7.

10, Fig. 1, is the eyelet box or magazine, mounted to oscillate or rotate on the upper end of the eyelet-track 11, this track being secured to a cylindrical slide l2, mounted in guides 13 on the head l. On the lower end of this slide isa stud or pin 14, which engages a camp-slot l5 in a rocker 16, mounted on the head 1, and'when the set 7 is moved upward a stud 17 thereon engages the rocker, rocks it, and'moves the track ll back out of the way. However, on the upper end of the eyelet-set 7 is a pin 7l, which as the set rises passes upward through the terminal eyelet in the track, so as to engage and hold it, and as soon as this engagement is eected the stud 17 engages the rocker 16 and moves the track back out of the way.

Mounted to swing laterally with a pin 1S, forming a vertical hinge axis, is an arm 19. This arm carries at its free end the clenching-anvil 20, which is xed or stationary, and the punch-carrier 2l and punch 22, secured therein. The punch-carrier plays in a guideway in the arm, is normally alined with the IOO eyelet-set, and is operated by a bent lever 23, fulcrumed at 'y on the arm 19. The pendent arm 23 of the bent lever 23 is adapted to be acted on bythe upper arm of a lever 24, fulcrumed at ,e on the head or frame of the machine, and the lower arm of the lever 24 is in the path of a stud 25, which projects laterally from the head of the rod 8, as seen in Fig. 4. This stud is so placed that it engages the lever 24 and through it and the bent lever 23 actuates the punch at the iirst part of the punching and setting operation. The lower arm of the lever 24 is bent outward and downward, so as to form a shoulder at 24, and the stud 25 impinges first on the lever below this shoulder. Then as the parts move it slides up and disengages itself from the lever at this shoulder and at the completion of the punching operation, allowing the punch-carrier to be retracted by its spring. (Indicated in dotted lines in Fig. 2.) Such retractingsprings are common in punches and do not require special illustration. Any spring will serve. As the eyelet-set 7 continues to move upward and immediately after the punch is retracted a stud or pin 2G, projecting laterally from the eyelet-set, engages a cam 27 on an arm 2S, fixed on the hinge-pin 18, and displaces said cam and arm laterally, thus swinging laterally the arm 19 and bringing the anvil 2O into alinement with the ascending eyelet-set 7. As the eyelet-set continues to move upward, and immediately after the anvil has been shifted into alinement, the pin 7 in the set engages the terminal eyelet in the track, and the latter is moved back out of the way by the stud 17 and rocker 16. The ascending eyelet-set carries the eyelet up and inserts it from below into the hole punched, pressing it upward, finally, and clenching it on the anvil 20. When the operation is thus completed, the spring 5 retracts the parts.

It may be explained that the rocker 16 is of such shape that when the set 7 moves upward the stud 17 engages a projecting part thereof, rocks the rocker, and passes on, and in the downward movement of the set the stud 17 engages another arm on the rocker and rocks it back again. Thus the rocker is moved in both directions positively by thel stud 17.

It may be noted here that in the construction shown the eyelet-box 10 is oscillated by a link 29 (which couples it loosely to the head 1) whenever the box is moved to and fro by the displacement of the track. This is a known device and has no special relation to the present invention.

The stud 25 in the head of the rod 8 is beveled in the manner of a latch-bolt, and said stud is backed by a spring, so that it may be pressed in as it wipes over the lower end of the lever 24 in going back. This feature is illustrated in the detail view, Fig. 7.

The stud or pin 7 in the upper end of the eyelet-set 7 is adapted to be pressed back or in when it impingcs upon the central nipple of the anvil 2O in clenching the eyelet. This feature is illustrated in lFig. S, wherein 7b is the spring behind the pin.

The punch 22 is a die-punch and when driven down enters a lower die 30 on the arm 19. The supporting-plate 6 is slotted, asindicated in Fig. 5, to permit the die 30 to play when the arm 19 is displaced laterally. The lateral displacement of the arm 19 displaces the lever 23 also; but this displacement is not enough at the point of contact of the lever 24 with the pendent arm 23 to disengage them.

The cam 27 is of such a form that when displaced by the stud 26 the latter holds the arm 19 displaced until the eyelet-set 7 descends or is retracted. The arm 19 is brought back to its normal position by a leaf-spring 3l. (Seen in Fig. This is a simple flat spring secured to the head 1, with its free end bearing on the arm 19. Any known spring construction may be employed to effect this object.

In the principal figures the arm 19 is shown in its simplest form with two integral jaws or branches, the upper branch carrying the punch and the lower branch the die 30; but the construction seen in Fig. 9 is sometimes preferred. In this view the lower branch 19' is not integral with the upper branch, but is mounted on the pin 18, so that when a setscrew 19'l or other means for securing it is loosened the branch 19 maybe swung around to one side, thus affording ready access to both the punch and die for removal or substitution. For example, the die-punch may be substituted by a cutting-punch and the die 30 by a cutting-plate.

The employment of the cylindrical slide l2 effects an important economyin the construction, as it may be turned and the guides or bearings therefor bored in the guide-lugs 13 on the head. To prevent the slide from rotating or rocking in its bearings, a flattened face 12 is formed on it, and a block 13 is screwed onto the lug 13 to bear on said face. Preferably there will be a flattened face and block at each lug 13. The eyelet-track 11 is secured by screws to a long support or carrier 11', and this carrier is secured to the Slide 12.
